Title: Detecting method for failure in array of core in quad of quad cable
Inventor: SUZUKI FUMIO
IPC: G01R31/02
Filed: 1981-06-03
Abstract: PURPOSE:To obtain a stable signal free of modulation due to the rotation of a quad by inducing an AC electric signal at each core by using a revolving magnetic field when cores are stranded into a quad, and detecting it by electrostatic coupling at each core before the quad stranding. CONSTITUTION:A revolving magnetic field generation part 15 consists of induction coils 15A-15D arranged radially around a quad cable 14 at pi/2 angle intervals, and pi/2 phase shifting circuit 17 for pi/2 phase shifting, and this generation part 15 produces a revolving magnetic field by using a two-phase alternating current. The revolving speed of this revolving magnetic field is set much higher than the revolving speed of a quad, and this revolving magnetic field induces AC electric signals at cores 2A-2D. Therefore, detected signals are never modulated by the rotation of the quad and an electrostatic detection part 3 and a differential detector 7 detects a fault of the array of the cores in the quad of the quad cable.

Title: Driving method for display device
Inventor: OGAWA TETSU
IPC: H04N5/66
Filed: 1986-04-14
Abstract: PURPOSE:To make an excellent display even when the one characteristic of a switch element is not sufficient by constituting a scan signal to be supplied to one scanning line by using plural pulses and making >=1 pulse supplied to the scanning line overlap with pulses supplied to another scanning lines. CONSTITUTION:The scanning line of the (i+1)th line consists of two successive pulses A and B, whose pulse width is shorter than a 1H (one horizontal scanning) period and corresponds to a horizontal blanking period when a TV signal is displayed. At this time, the normal display signal of the (i+1)th line is written in picture elements in the period of A. The pulse B overlaps with a period in which the normal display signal of the (i)th line is written in picture elements. Consequently, a display signal which should be supplied to the (i)th scanning line originally for the 1st time is supplied to the (i+1)th line and then the normal display signal is supplied. This driving method is used to extend substantially the period in which TFT is on, thereby evading a voltage drop due to the deficient on state of the TFT and the influence of the asymmetry of a liquid crystal applied effective voltage between fields.

Title: Alumina board for plane antenna
Inventor: ITOU TOSHIIKU
IPC: C04B35/10
Filed: 1993-04-13
Abstract: PURPOSE:To provide a plane antenna use alumina board with a high gain and excellent stability in the resonance frequency and suitable for miniaturization of the system by selecting specifically a linear absorption coefficient of a dielectric board. CONSTITUTION:The antenna consists of a dielectric board 1, a microstrip element 2 and a ground conductor 3. Then a high gain ratio is realized by using the alumina board whose linear absorption coefficient (mu) is 0.75(1/cm) or over for the dielectric board 1. Furthermore, when there is a correlation between the linear absorption coefficient (mu) and a specific dielectric constant (epsilon) of the dielectric board 1 and dispersion in the specific dielectric constant (epsilon) of the dielectric board 1 is large, the dispersion in the resonance frequency (fo) is high. Thus, when the dispersion in the linear absorption coefficient (mu) is within 0.10(1/cm), the dispersion in the resonance frequency is small and the individual antenna characteristic is checked after the microstrip element 2 is formed to omit a process of fine-adjusting the element 2.

Next, with respect to the relative position of the work 21 and the tool 20, the work 21 and the tool 20 are moved to a height position (a) to enable a circular arc to be worked promptly in the tangential line direction of the circular arc to be desired upon finishing the circular arc working. Further, the table is moved until the tool 20 reaches a position b as an approaching operation. After that, the table is moved so that a start point and an end point are set to the position (b) and a circular arc interpolation is executed by diameter of the circular arc to be finished. Finally, the table is moved until the tool 20 reaches a position (c) as a releasing operation. As described above, in the case of circular arc working, the working precision upon up-cutting work is always improved.
